BROADBAND vs. BASEBAND
-Broadband and baseband are the two types of signaling methods that networks employ.
Baseband:
-A baseband transmission is carried over a single wire using digital signaling.
-Baseband communications are bidirectional. Signals can be both sent and received (but not simultaneously.)
- Time Division Multiplexing (TDM) allows multiple signals to be sent via baseband transmissions on a single cable. TDM allocates the multiple signals across time slots.
Broadband:
-Broadband transmissions are analog transmissions.
-The media used in broadband transmissions is split into two channels to allow signals to be both sent and received.
-Frequency Division Multiplexing (FDM) is used to create multiple broadband channels.
